The difference depends upon the specific photosynthetic
process used by each plant. Honey "should" be made from
"C3" (Calvin cycle) plants rather than "C4" (Hatch-Slack
cycle).

The ratio of C-13 to C-12 is exactly what varies between C3
and C4 type plants. Carbon-14 is a non-issue here.
A Google search on "C3 photosynthesis", "C4 photosynthesis",
"Calvin cycle", or "Hatch Cycle" ought to give you the information
you want.
